Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding device technology, and in particular to an assembled electromagnetic shielding shell. Background Technology

[0002] Electromagnetic shielding technology is a technique to prevent electromagnetic interference between electronic devices or components. It involves enclosing the receiving circuit, equipment, or system with a shield to prevent them from being affected by external electromagnetic fields and to prevent interfering electromagnetic fields from spreading outwards. In existing technologies, conductive or magnetic metal materials are typically used to create a sealed casing, inside which the electronic product is placed. This casing is usually a box-like structure. For ease of placement and removal of the electronic product, the casing is often designed as a single unit. If one side panel of the casing is damaged, the entire casing must be replaced, resulting in high maintenance costs. Furthermore, the casing opening is fixed to a door with bolts, making installation and disassembly inconvenient. Utility Model Content

[0023] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0024] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 An assembled electromagnetic shielding shell includes a base body 1, four side plates 2, a cover plate body 3, and four support pads 4. The base body 1, the four side plates 2, and the cover plate body 3 are all made of aluminum alloy or copper alloy. The base body 1 is provided with a square placement boss 101. Positioning grooves 102 are opened around the placement boss 101. Each side plate 2 is arranged around the placement boss 101. Each side plate 2 is provided with a positioning element 201 that is inserted into the positioning groove 102. The bottom surface of the side plate 2 abuts against the base body 1. The positioning groove 102 is T-shaped. The positioning element 201 and the positioning groove 102 abut against each other. The four side plates 2 are respectively arranged around the placement boss 101 of the base body 1 by means of the positioning groove 102 and the positioning element 201, so that each side plate 2 and the placement boss 101 form an upward-opening cavity for placing electronic equipment or electronic components.

[0025] An edge groove 202 is formed between two adjacent side plates 2 and the base body 1. The edge groove 202 is provided with a mounting hole 103 that penetrates the base body 1. An edge post 301 is provided around the cover plate body 3, which is inserted into the edge groove 202. The bottom surface of the edge post 301 is provided with a fastening hole 302. The edge groove 202 formed between the two adjacent side plates 2 and the base body 1 allows the cover plate body 3 to cover the opening of the cavity by inserting the butt post and the edge groove 202, guiding the cover plate body 3 to be aligned and assembled on the base body 1, ensuring that each fastening hole 302 corresponds to and is connected to each mounting hole 103. The support pad 4 is provided with a fastening rod 401. The fastening rod 401 passes through the mounting hole 103 and is threadedly connected to the fastening hole 302 to fix the cover plate body 3 on the base body 1, ensuring good assembly and sealing of the electromagnetic shielding shell. The disassembly and assembly operations can be completed by operating each support pad 4, which is relatively convenient. The electromagnetic shielding shell adopts a split design, which means that when maintaining or replacing the side plate 2, only the damaged side plate 2 can be replaced instead of the entire shell, which facilitates maintenance and replacement operations and reduces maintenance costs.

[0026] The top surface of the side plate 2 is provided with an alignment groove 203, which is connected to the corresponding corner groove 202. The corner post 301 is provided with an alignment member 303 inserted into the alignment groove 203. The outer wall of the alignment member 303 is provided with a positioning groove 304, and the inner wall of the alignment groove 203 is provided with a positioning protrusion 204 that cooperates with the positioning groove 304. When the alignment member 303 is inserted into the alignment groove 203, the positioning protrusion 204 corresponds to the positioning groove 304 and the two parts are in a concave-convex fit, making the connection between each side plate 2 and the cover plate body 3 more reliable, ensuring the structural stability of the electromagnetic shielding shell. Furthermore, when the operator operates each support pad 4 to perform disassembly, the operator can remove the cover plate body 3 and drive each side plate 2 to detach from the placement protrusion 101, thus facilitating the operator to directly operate the electronic equipment or electronic components on the placement protrusion 101. The operator only needs to apply pressure to the side plate 2 to completely detach the positioning protrusion 204 from the positioning groove 304, making it easy for the side plate 2 to be pulled out relative to the cover plate body 3 for subsequent maintenance and replacement.

[0027] refer to Figure 1 , Figure 5 , Figure 6 The top surface of the cover plate body 3 is provided with a placement groove 305 for inserting the support pad 4 at the position of the corner post 301. This allows the two electromagnetic shielding shells to be stacked vertically and vertically by inserting and cooperating with the support pad 4 through the placement groove 305. The depth of the placement groove 305 is less than the thickness of the support pad 4, so that a gap is reserved between the two electromagnetic shielding shells after stacking to form an air convection channel, thus avoiding heat accumulation caused by the two electromagnetic shielding shells being tightly attached.

[0028] refer to Figure 1 , Figure 2 , Figure 3 The base body 1 has several first pairs of interfaces 104 arranged in a linear array on one side and several second pairs of interfaces 105 arranged in a linear array on the other side. The placement boss 101 is hollow inside and has several cooling pipes 106 arranged in a linear array inside. The two ends of the cooling pipes 106 are connected to the first pairs of interfaces 104 and the second pairs of interfaces 105 respectively. The first pairs of interfaces 104 and the second pairs of interfaces 105 can be used as the input and output ends of the heat dissipation medium, respectively. Each first pair of interfaces 104 and each second pair of interfaces 105 can be connected to an external air pump or water pump to dissipate heat from the placement boss 101 and prevent the electronic equipment or electronic components inside the electromagnetic shielding shell from malfunctioning due to overheating.

[0029] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
